We have a 98 vette with a Magna charger running 6 pounds of boost. The car is stock other than the blower with 45500 miles. I had the trans happy before the blower, but now it wants to blow thru the 1-2 shift and the 2-3 shift. I have tried many adjustments with line pressure, rpm, millamps, etc. Spent many hours on here reading up. I have now went back to the first tune and the trans will not shift 1-2 untill 3750 or so rpm with light throttle. About 40% throttle will will shift from 1 to 2 at 4500. No easy/nice shifts as before. Is it possible that there is a internal problem that is hanging the 1-2 shift and not allowing this to happen at a low line pressure? I have enclose the first tune that came with the blower and my latest shot at making the tranny happy.
thanks
Mark
